  • Unity Continues Crunching More Out Of Crunch Texture Compression

    Unity is one of the big public users of the open-source Crunch DXT texture compression library. While it's no longer maintained by Rich Geldreich / Binomial, Unity has continued advancing this open-source code to further improve the compression ratio and speed.

    For months Unity has been talking about their promising findings with Crunch. But this is the project that Rich Geldreich, the former Valve developer, previously expressed regret having open-sourced all of it. While he is on to working on better and more advanced technologies at his Binomial startup, Unity is working to squeeze more out of this open-source library.

  • Improving EFL Graphics With Wayland Application Redraws

    Under X, application redraws are tricky to do without tearing because content can be updated at any chosen time with no clear feedback as to when the compositor will read it. EFL uses some clever tricks to this end (check out the state of the art X redraw timing for yourself), but it’s difficult to get right in all cases. For a lot of people this just works, or they’re not sensitive to the issue when it doesn’t.

  • Improved Wayland Application Redraws Coming To Enlightenment's EFL

    Samsung's Open-Source Group has been working on making their Wayland support in the Enlightenment Foundation Libraries (EFL) even better.

    The latest Wayland work on the Enlightenment/EFL front has been improving the application redraw process. The EFL toolkit with the upcoming v1.21 release will now be hooking into Wayland's frame callbacks to better dealing with drawing, only drawing when necessary, and doing so without the possibility of tearing.

  • AMD FreeSync For Tear-Free Linux Gaming - Current State In 2017

  • AMD open sources its Vulkan

    AMD's Vulkan Linux driver which was initially going to be closed-source and open-sourced when it was finished, is now totally open sourced.

    AMD has released the source code to its official Vulkan Linux driver, just in time to make the Christmas best sellers’ list.

  • AMD To Deliver On Its Promise Of An Open Sourced Vulkan Linux Driver Very Soon

    If I had to guess, I’d say AMD really didn’t want to begin yet another year with its open source Vulkan driver still in hiding, so here we are: it’s finally happening. As Phoronix notes, AMD promised the world over two years ago that it would open source its Vulkan driver for Linux, but few probably realized it’d actually take quite this long to see the day. We can be thankful that this driver didn’t just wind up like some Half-Life episode.

  • VKD3D Is Beginning Flight As Wine's Direct3D 12 To Vulkan Library

    Back at WineConf 2017 VKD3D was announced for bringing Direct3D 12 to Wine by implementing Microsoft's latest graphics API atop the Vulkan graphics API. The initial code for this new library is beginning to take shape.

    VKD3D is a long-term play for getting viable Direct3D 12 support working within Wine. As noted back at WineConf, this library is being developed independently of the Wine Git repository. This will potentially allow in the future others to make use of this D3D12-to-Vulkan code without pulling in Wine entirely, should porters look to this project for easing their process of getting Windows games running on Linux, etc.

  • Wayland's Weston Sees Patches For FreeBSD, Fractional HiDPI, Rust Bindings

    A new contributor to the Wayland/Weston camp has been working on several improvements to the Weston reference compositor.

    Improvements made to Weston via unmerged patches include adding FreeBSD support to Weston, static linking for backends and gl-renderer, Rust bindings for libweston, and fractional HiDPI scaling support.

  • Disjoint Timer Query Added To Mesa For Reporting Accurate OpenGL Timing Data

    The latest OpenGL extension added to Mesa by Intel developers is the rather new EXT_disjoint_timer_query.

  • mesa 17.2.7

    The current queue consists of a variety of fixes, with a sizeable hunk in the shared GLSL codebase.

    Whereas for individual drivers - i965 has a crash fix for when playing various Valve games, r600 and nouveau have tweaks in their compiler backends. Fast clears on radeonsi and RADV are better now, while the VAAPI encoding is playing nicely with GStreamer.

  • Mesa 17.2.7 Released For Those Not Yet On Mesa 17.3

    Emil Velikov of Collabora has announced the release today of Mesa 17.2.7 as the latest point release for this older stable branch of Mesa.

    If you are a devoted Linux gamer or at all care about the best features and performance, it's best you migrate to Mesa 17.3 if you are not habitually riding Mesa Git. But for those still using the Mesa 17.2 series from last quarter, the seventh point release is available.

  • Happy Holidays: AMD Finally Pushing Out Open-Source Vulkan Driver

    Ahead of the Vulkan 1.0 debut nearly two years ago, we heard that for AMD's Vulkan Linux driver it was initially going to be closed-source and would then be open-sourced once ready. At the time it sounded like something that would be opened up six months or so, but finally that milestone is being reached! Ahead of Christmas, AMD is publishing the source code to their official Vulkan Linux driver.

  • The Feature Differences Now Between AMD's Two OpenGL & Two Vulkan Linux Drivers

    For modern AMD graphics cards there are two OpenGL drivers and two Vulkan drivers available to Linux users/gamers that support the same modern AMD GPUs, not counting the older AMD Linux drivers, etc. Here's a rundown now on how those drivers compare.

    With AMDGPU-PRO 17.50 now allowing you to mix and match driver components and AMD finally open-sourcing their official Vulkan driver, the scene may be even more confusing about which AMD Linux driver(s) to use depending upon your use-case.

  • AMD Moving Forward In Their RadeonSI Support For ARB_gl_spirv

    AMD open-source developer Nicolai Hähnle has spent the past few months working on the ARB_gl_spirv extension as mandated by OpenGL 4.6. Some of the prep work for supporting that extension has landed in Mesa 17.4-dev Git.

    ARB_gl_spirv is about bringing SPIR-V support to OpenGL drivers, the IR shared by Vulkan and OpenCL 2.1+. ARB_gl_spirv allows for loading SPIR-V modules into OpenGL programs and allows for GLSL to be a source language in creating SPIR-V modules. This is basically for creating better interoperability between OpenGL and Vulkan/SPIR-V.

  • Mesa Glthread Gets Adds Another Game, AMDGPU Winsys Gets Performance Workaround

    This week has started off to being another busy time in Mesa Git just ahead of the holidays.

    First up, Mount & Blade: Warband is the latest game to be white-listed by the Mesa glthread functionality for enabling OpenGL threading on this Steam Linux game. Mount & Blade: Warband was actually whitelisted back in July but then disabled a few days later as it turned out not to be working.

Graphics/Benchmarks

This system was running Ubuntu 17.10 and the configurations tested included:

- Ubuntu 17.10 in a "stock" or "out of the box" experience when using its Linux 4.13 kernel, GNOME Shell 3.26.1 with Wayland, and Mesa 17.2.2 atop an EXT4 file-system.

- Upgrading the Ubuntu 17.10 system to Linux 4.15 Git for showing the power consumption when using the very latest kernel cycle.

- This Ubuntu 17.10 + Linux 4.15 system then with Intel PowerTop installed and changing all the tunables to their "good" values for maximum power-savings.

- Installing TLP and using its default power-saving options.
